Abstract
Combustible gases from pulverized solid fuel are generated by semi-coking the pulverized solid fuel in a reactor in the absence of oxygen to produce a solids stream that includes carbonaceous material and a gas stream that includes hydrocarbon gases and tar fumes. The carbonaceous material in the solids stream is gasified in a fluidized bed using steam and hot air to produce an output stream that includes combustible gases and coke particles. The output stream is combined with the gas stream to form a combined stream which is separated into a combustible gas stream and a hot particulate stream. At least a part of the hot particulate stream is applied to the reactor.
